The Redding The UltraMag Reloading Press is unique among single-stage reloading presses, because it features a large frame opening as well as a super-long useable ram stroke. These features combine to make the Redding The UltraMag Reloading Press ideal for loading oversized cartridge cases. Not only does the Redding The UltraMag Reloading Press accommodate oversized cartridges, but it features an innovative long-link compound leverage system that gives you greater mechanical advantage than nearly any reloading press out there. This press is also made with a cast-iron frame to ensure a lifetime of dependability and durability.
